CHIROGRAPH.

SPECIFICATION forming part of Letters Patent No. 665,561, dated January8, 1901.

Application filed April 17, 1900. Serial No. 13,212. (No model.)

To all whom it may concern:

Be it known that I, ALBERT B. ANDERSON, a citizen of the United Statesof America, residing at Elizabeth, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inOhirographs, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to certain new and useful improvements inchirographs, and it is particularly adapted for use in positioning andsupporting the hand when writing, so that it will permit of obtainingthe three movements necessary in penmanship, which are the fingermovement, the muscular or forearm movement, and the whole-arm movementused for scroll and engrossing work, and is further adapted to assist inobtaining the proper position of the hand to enable the scholar to writein the proper manner as called for by the various movements, and to thisend the invention has for its object to construct a chirograph whichwill be extremely simple in its construction, strong, durable, efficientin its use, and compara tively inexpensive to manufacture.

With the above and other objects in view the invention finally consistsin the novel construction, combination, and arrangement of parts to behereinafter more fully described, and specifically pointed out in theclaim.

In describing the invention in detail reference is had to theaccompanying drawings,

chirograph is formed from a single piece of wire bent at one end to forman eye 2, which is adapted to receive the pencil 3, and at its other endthe Wire is bent into a supporting- 1 loop 7, which has a slight springaction by reason of its free end not being brought into contact with thewire. Adjacent to the eye 2 the wire is coiled helically to form an eye4, which is adapted to receive the index-finger, and adjacent to thesupporting-loop 7 the wire is similarly coiled to form an eye 6 for thereception of the fourth finger of the hand. These two eyes are connectedby the cross-bar 5, which is slightly bowed or curved upwardly toproperly conform to the hand.

The mode of using will be readily apparent, the index-finger beinginserted in the eye 4 and the fourth finger in the eye 6, with thecrossbar 5 lying under the fingers and the supporting-loop 7 restingupon the paper or table. The pencil is placed in the eye 2 and properlypositioned between the ball of the thumb and front or index finger.

It is thought that the many advantages of my improved chirograph can bereadily understood from the foregoing description,taken in connectionwith the accompanying drawings, and it will be noted that variouschanges may be made in the details of construction without departingfrom the general spirit of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

As a new article of manufacture, a chirograph which is formed from asingle piece of wire having oneextremity formed into a pencil-receivingeye 2 and the other extremity formed into a spring supporting-loop 7,the wire being coiled adjacent to said eye and loop to formfinger-receiving eyes 4, 6, adapted to respectively receive the indexand the fourth finger of the hand and connected by a curved cross-bar 5adapted to lie underneath and conform to the curvature of the fingerswhen the device is in position on the hand, substantially as described.

In testimony whereof I affix my signature in the presence of twowitnesses.

ALBERT B. ANDERSON.
